# Re: [isabelle] LaTeX Theorem Environments for Definitions and Proofs

There exists an antiquotation @{datatype xyz} you can try. If you want to
display actual parts of your Isabelle theory you can either include the
documentation into the theory, or you can show definitions by antiquotations (eg
@{thm f.simps[no_vars]}) or perform some trickery described in the wiki
https://isabelle.in.tum.de/community/Generate_TeX_Snippets or in more detail in
the development version of the LaTeX Sugar manual.
